PSA if you run a DRAM-less NVME SSD in a Raspberry Pi 5/500+ don't forgt to set
nvme.max_host_mem_size_mb=64
in your /boot/firmware/comdline.txt
after a reboot look in your dmesg for a line that says something like
nvme nvme0: allocated 40 MiB host memory buffer.
That's how much your drive actually requests.
Adjust the value accordingley in cmdline.txt and reboot again.
Raspberry Pi in there limetless wisdom have disabled HMB in fact they had patched it out in earlier kernels.

HMBはNVMe SSD低価格化の切り札!?東芝メモリ「BG4」で実力検証 (3/6) https://ascii.jp/elem/000/001/829/1829152/3/
HMB容量をOSに伝えるプロファイル内の定義がでっかいのに、ハードウェア側での受け入れ可能容量が小さいとか、パフォーマンスアップのためにズルいことやったんじゃないかと疑いたくなるポンコツ問題よね…
